A new algorithm to simulate all solar components and optimum slopes, Bopt, based on new
models for direct normal beam and diffuse radiation and an analytical model to predict Bopt,
developed at the University of Botswana ...

The charge transfer between metals and some solution-cast polymers has been investigated
by employing intermittent soft contact under a controlled condition. The result of our
measurements reveals that the measured charge ...

The azimuthal surface nucleation field of an infinitely long type II superconducting cylindrical filament is calculated
from the linearized Ginzburg-Landau equation for the order parameter. A current is thought to be ...

The Hopkinson effect is the increase of magnetic susceptibility with temperature from near room temperature to near the Curie point. Although this effect has been known for more than a century, it has not been effectively ...

Indium tin oxide (ITO) thin films were prepared by RF sputtering of ceramic ITO target in pure argon
atmosphere at a high base pressure of 3 10 4mbar without substrate heating and oxygen admittance.
The use of pure argon ...

Indium tin oxide (ITO) thin films were prepared by RF sputtering of ceramic ITO target in pure argon atmosphere at a high base pressure of 3×10−4 mbar without substrate heating and oxygen admittance. The use of pure argon ...

Optical properties of Pb doped ternary Ge-Sb-Te chalcognide films prepared by thermal evaporation have been studied in
the visible and near-infrared spectral regions. The straightforward analysis proposed by Swanepoel has ...

The study of interaction of photons with matter finds
wide application in areas such as industry, medical
radiation dosimetry and radiation shielding. A careful review of these measurements indicates that
the studies ...

A calculation is presented on the scattering rates of electrons via the bulk spectrum of longitudinal
optical phonons near a current-carrying core of radius R employing the Frohlich interaction Hamiltonian.
The electrons ...

Fault-plane solutions of an earthquake can provide information about the type of fault. We report on the calculation of the
fault-plane solutions of the earthquake that occurred on the morning of 18 May 2001 and was felt ...

A comparative study of the traditional PZT ceramics and new single crystals is critical in selecting the best material and
optimization of transducer design for applications such as conversion of ambient vibrations into ...

The granite-greenstone terrain of south-central Zimbabwe, encompassing the Belingwe (Mberengwa) greenstone belt and sections of
the Great Dyke, provides important constraints on models for the evolution of the Zimbabwe ...

The Limpopo Belt of southern Africa is a Neoarchean orogenic belt located between two older Archean provinces, the Zimbabwe craton to the north and the Kaapvaal craton to the south. Previous studies considered the Limpopo ...

Although several studies have recommended removal of secondary components of magnetic remanence by zero-field cycling from room temperature to a temperature much lower than the low temperature transition for magnetite ...
